In this context, it is certainly of interest
to endow PLA with antibacterial properties (and intensive
ultraviolet absorption) and addition of ZnO nanoparticles
to PLA could represent a relevant approach
Unfortunately,
the addition of untreated ZnO nanoparticles into
PLA at melt-processing temperature leads to severe degradation
of the polyester matrix, ascribed to the transesterification
reactions and ‘unzipping’ depolymerization of PLA.
By contrary, as reported elsewhere
